I've been starting to analyse videofluoroscopies as part of my dysphagia competency program and thought it would be usefull to compare my observations to the structured reports patients are given. Here goes no. 1.

Clinical Report
|
Solids
Delayed swallow
trigger, residue in the valleculae, able to clear residue with a cough,
decreased sensation?
Fluids
Tipped back –
decreased oral control, delayed swallow trigger, residue in valleculae, penetration,
able to clear residue with a second swallow
Summary
Oral stage – reduced coordination of chewing and reduced
base of tongue to pharyngeal wall approximation.
Pharyngeal stage – delayed swallow trigger, significant
valleculae residue, penetration but no aspiration.

Oral
Phase:
Lip closure was slightly reduced resulting
in mild lip spillage.
Tongue control was adequate for cohesive
bolus formation and for oral to pharyngeal transfer.
Tongue function was slightly reduced
resulting in mild oral residue, piecemeal oral clearance and, on fluids,
premature spillage into the pharynx to the level of valleculae sinus.
Chewing was slightly reduced due to reduced
jaw movement and tongue weakness with decreased range of movement.
Palatal elevation was adequate resulting
in complete velopharyngeal seal.
Pharyngeal
Phase:
Initiation of the swallow reflex occurred
when the bolus reached the level of the valleculae. This was considered to be
slightly delayed.
Base of tongue to posterior pharyngeal
wall approximation was reduced resulting in poor bolus propulsion through the
pharynx. There was subsequent
mild base of tongue and valleculae residue post swallow. There was evidence
that clearing soft and normal diet residue from the valleculae was more
effortful than clearing yogurt; indicated by facial expression, reported
feeling of the bolus sticking and effortful swallow, also cough triggered in
response to normal bolus, although there was no evident
penetration/aspiration.
Hyolaryngeal excursion was adequate to
facilitate epiglottic to arytenoid closure and upper oesophageal sphincter
opening.
Pharyngeal contraction was slightly
reduced resulting in mild valleculae residue after the swallow.
There was no evidence of aspiration
during the study.
There was trace penetration of the
laryngeal vestibule above the level of the vocal cords with normal fluids but
no penetration into the subglottic space. The trace penetration of thin
fluids was cleared on the initial swallow. There was no penetration of the
laryngeal vestibule with food, although a clearing cough was triggered on
normal bolus.
Compensatory
Techniques:
The following strategies were trialed with
thin fluids:
Multiple spontaneous swallows were
effective to clear base of tongue and valleculae residue.
Prompted smaller sips were beneficial to
achieve less effortful swallow.

SUMMARY
- Slightly reduced tongue function.
There was mild to moderate pharyngeal phase
dysphagia characterised by:
- Delayed initiation of the swallow reflex
- Reduced base of tongue to posterior pharyngeal wall approximation and reduced pharyngeal contraction resulting in:
- poor bolus propulsion through the pharynx
- mild base of tongue and valleculae residue post swallow
There was no evidence of aspiration and
only trace penetration, which was cleared on the initial swallow, during the
study.
The findings of this assessment are
consistent with generalized progressive muscle weakness secondary to Muscular
Dystrophy.
RECOMMENDATIONS:
- Thin fluids
- Soft moist diet – to help keep the bolus more cohesive and to reduce valleculae residue.
e.g. having
extra gravy/sauce with your food.
- Small mouthfuls/sips
- Allow time for multiple clearing swallows to clear residue before taking another mouthful/sip
Reflection
· ANATOMY: The adult larynx is located around the
level of C3-6, the hyoid can be seen on the VF and is a marker, as is the
epiglottis.
· Focusing on a) Oral Phase b)Transfer and c)
Pharyngeal phase was useful rather than everything as a whole.
· Looking for aspiration down the airway anterior
to the oesophagus was useful.
